well, what do you mean by it? What it says to me is very literal, A equals B and either both are greater than C or at least B is greater than C. I don't see how you get that from what's going on. Do you mean something else?

I mean that A and B are equally bright and that both are brighter than C

I think there's no current passing through B at all. My reasoning: why would the electrons go through path with a resistor that does not lead to the negative terminal of the battery when they have the choice to take a resistless (ideally) path that leads to the negative terminal of the battery.

Not yet, but I am curious. I'll look it up. Is it when there is a gap somewhere on the circuit so the current pass? What is it useful for?

It is the technical term for a "gap" in the circuit, so current can't flow through it.
A circuit needs to be closed for the flow of current. Here, no current flows through bulb B since there's no closed path.
